With an enormous market size of $156 billion, the medical device industry in the United States remains the largest in the world. Companies in the medical device industry consist of articles, instruments, apparatuses, or machines that are used in the prevention, diagnosis or treatment of illness or disease, or for detecting, measuring, restoring, correcting, or modifying the structure or function of the body for some health-related purpose. Although patients are the end-users of medical devices, manufacturers ideally focus their efforts towards selling their products to healthcare providers who in turn use them to serve the needs of patients.
Majority of the companies in the US medical device industry are concentrated in regions known for other high-technology industries, such as microelectronics and biotechnology. The states with the highest number of companies in the medical device industry include New York, California, Florida, Michigan, Pennsylvania, Massachusetts, Minnesota, Illinois, and Georgia. Compared to several other industries including telecommunications, automotive, and defense, the medical device industry invests a higher percentage of their yearly revenues into product innovation, reflecting the competitive nature of the industry and constant innovation and improvement requirements of existing technologies.
